一步步引导新手设置CP5611卡，有图片提示，非常详细。按说明做都能成功。(CP5611)

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)

本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案(not build this program in addition to case-insensitive outside of the coding process required prior to the establishment of the letters after the value of the text pieces can Win OK this program read from the file into the text, compiled into the paper, not directly on the screen appeared the answer)

in this simulation we implement LTE schemes frequency reuse and we analysed interference co-chennel

毕业设计的基于8QAM+zcz序列的准同步CDMA通信系统仿真(　　　This article will be given below 8QAM+ ZCZ sequence sets up method and analysis, will further introduce the relevant definitions zero correlation sequence and some properties and characteristics, including non-cycle related, cycle-related, Qi cycle and other characteristics. The reason why is because the study of these theories using this sequence, in the Gaussian channel conditions and system performance in terms of interference is very similar to the synchronization system and the system performance is far superior to an asynchronous system, and the extended sequence comparison the original sequence has better performance.)

模型是进行控制与稳定性分析的基础，可以服务于仿真、系统行为分析、系 统内在机理分析、控制、预测、监督与故障诊断等目的。因此，建立系统的模型 已成为许多科学研究与工程实施的首要问题。(Model is the basis for control and stability analysis, can serve simulation, system behavior analysis, the internal mechanism of the system analysis, control, forecasting, monitoring and troubleshooting purposes. Therefore, the establishment of the system model has been implemented for many scientific and engineering the most important issue.)
